Extra dot on seven-segment display?

(1/1)

radar_macgyver:
I have a few Lite-on LTC-4727JR seven-segment displays with four digits, four decimal points, a colon and a mysterious extra dot (marked L3 in the data sheet). Anyone know what the extra dot is for?

chriva:
Degrees most likely :)
Ever noticed the circle next to C and F?

WattsThat:
Agree, it’s degrees. It’s a multi-purpose clock display. Bog standard stuff.

radar_macgyver:
Makes sense, thanks!

Doctorandus_P:
This used to be done by putting the rightmost display upside down.
